USPs of the RFDEW anti-drone system
The new weapon system tested by the British soldiers is different from the DragonFire. The DragonFire is a laser-directed energy weapon that uses a laser beam of light to kill unmanned aerial vehicles (UAVs) and drone swarms.

In stark contrast, the RFDEW uses radio waves to take down UAVs.

“The weapon uses high frequency waves to disrupt or damage critical electronic components inside devices such as drones, causing them to be immobilized or fall out of the sky,” the UK Ministry of Defense said in the release.

It also stated that the RFDEW can neutralize targets in a range of 0.62 miles (1 km) immediately.

It is also quite inexpensive as compared to other counter-drone measures, as it can tackle drones at a cost of roughly just 13 cents (10 pence in UK currency) per shot.
